The complexity of skin architecture, along with diverse symptomatology and intricate pathogenesis of dermatological disorders, highlights the urgent need for novel therapeutic strategies. Effective treatment of impaired wound healing and chronic skin diseases, including atopic dermatitis and psoriasis, remains challenging. Phytoterapeutics are increasingly investigated for their dermatologic potential, with numerous natural products of established use. Proanthocyanidins (PACs), a subclass of polyphenolic compounds, renowned for their anti-inflammatory and antioxidant properties, are promising candidates for novel solutions. This review article synthesizes the recent 25 years of research on biomolecular mechanisms, pharmacological effects, and phytochemical aspects of PACs, in the context of treating inflammatory-related skin problems. The available data highlight pro-regenerative, pro-angiogenic, antioxidative, and anti-inflammatory effects of PACs in accelerating wound closure. Preclinical data suggest their potent ability to mitigate chronic skin inflammatory disorders, including psoriasis and atopic dermatitis. Moreover, their photoprotective properties translate to the prevention of UV-induced skin inflammation. However, critical knowledge gaps remain regarding clinical verification and structure-activity relationships of PACs as dermatologic agents. Further optimization of topical formulation systems for PACs is also pressingly needed. Bridging traditional phytotherapy with novel discoveries in molecular pharmacology and pharmaceutical technology could help to design innovative PAC-based approaches for treating inflammatory skin diseases and impaired wound healing.<\/jats:p>","DOI":"10.3390\/ijms262010116","type":"journal-article","created":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T13:07:22Z","timestamp":1760706442000},"page":"10116","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Proanthocyanidins as Therapeutic Agents in Inflammation-Related Skin Disorders"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6557-5786","authenticated-orcid":false,"given":"Aleksandra","family":"Prokop","sequence":"first","affiliation":[{"name":"Department of Pharmacognosy, Faculty of Pharmacy, Medical University of Lodz, Muszynskiego 1, 90-151 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2437-3242","authenticated-orcid":false,"given":"Anna","family":"Magiera","sequence":"additional","affiliation":[{"name":"Department of Pharmacognosy, Faculty of Pharmacy, Medical University of Lodz, Muszynskiego 1, 90-151 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8468-1365","authenticated-orcid":false,"given":"Monika Anna","family":"Olszewska","sequence":"additional","affiliation":[{"name":"Department of Pharmacognosy, Faculty of Pharmacy, Medical University of Lodz, Muszynskiego 1, 90-151 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,17]]},"reference":[{"key":"ref_1","first-page":"24","article-title":"Review of Skin and the Effects of Aging on Skin Structure and Function","volume":"52","author":"Fore","year":"2006","journal-title":"Ostomy Wound Manag."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"116","DOI":"10.1111\/imm.13152","article-title":"Skin Barrier Immunity and Ageing","volume":"160","author":"Chambers","year":"2020","journal-title":"Immunology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"455","DOI":"10.1089\/ten.teb.2020.0236","article-title":"Aloe Vera: A Medicinal Plant Used in Skin Wound Healing","volume":"27","author":"Liang","year":"2021","journal-title":"Tissue Eng.
